Freeing up storage space on an Android phone is a fairly simple task. Just follow the steps below to clean up as much room as possible.

1. Uninstall apps that you don't use. Go to Settings > Apps and uninstall all of the software that you don't use. Go to Settings > Apps and uninstall all of the software that you don't use. The space occupied by each app is indicated under its name - that's the space you should be expecting to gain.
2.Move or downsize your pictures. If you've had your phone for a while, then chances are that you've taken a bunch of pictures with it already. These are probably hogging quite a lot of data space so moving them over to a computer's hard drive would be a good idea.
3. Clear the cache. Your apps save chunks of data for later use - map information, graphics, sounds, temporary downloads, stuff like that. Over time, these temporary files might pile up regardless of whether they'll ever be used or not. Feel free to clear your cache by going to Settings > Apps and tapping on "Cached data".
